The report, provided to Breitbart News ahead of its late Sunday evening release, reviews internal Immigration and Customs Enforcement (ICE) metrics to conclude that the Obama administration released 35 percent—or 68,000—convicted criminal aliens back into the U.S. general population when they could have been deported. “The criminal alien releases typically occur without formal notice to local law enforcement agencies and victims,” CIS’s Jessica Vaughan, the report’s author, added.

By “criminal,” ICE means people who have been convicted of a misdemeanor or felony that is not a traffic violation. For instance, traffic violations like Driving Under the Influence of Alcohol or even vehicular manslaughter do not count toward this description of “criminal alien.” As for the definition of “alien,” ICE mostly means illegal aliens, though some are legal aliens when they are considered deportable legal aliens—which is possible for legal immigrants who have committed a serious crime, like a felony.

The documents also show ICE only deported a small fraction of the aliens they encountered overall.

“In 2013, ICE targeted only 195,000, or 25 percent, out of 722,000 potentially deportable aliens they encountered,” CIS’s Vaughan wrote. “Most of these aliens came to ICE’s attention after incarceration for a local arrest.”

This report comes out on the heels of a report from the office of Sen. Jeff Sessions (R-AL) last week which found that only .08 percent of the aliens deported in 2013 were not serial immigration law violators or convicted of serious crimes.
